BUCKLE Filed July 29, 1932 lNvENToR ATTORNEY Patented `luly 3, 1934UNTED STATES PATENT OFFICE BUCKLE York Application July 29, 1932, SerialNo. 625,567

2 Claims.

This invention relates to a buckle or slide, of the slotted-plate type,for the adjustable attachment of a strap to another strap or to theother endof the same strap; and the object thereof is to provide anefficient, cheap and otherwise satisfactory buckle for fasteningtogether the adjustinent straps of womens underwear and corsets or atthe back of a vest and at the waistband of trousers and overalls, andthe like.

In buckles of this type the strap will be more securely held againstlongitudinal displacement, especially where the slots are made fairlywide so that a strap can be easily threaded therethrough, if the middleor intermediate bar is elevated to a plane above that of the main bodyof the buckle, since it will then effect sharper bends in the strapwhich is threaded through the slots and over this bar. But in thepractical manufacture of these buckles, in dies which stamp out thebuckle from the plate or sheet and press up the middle bar by bending itat the ends where it joins the sides of the buckle, the middle bar canbe raised to a limited extent only, not sufficient to secure the bestresults, without fracturing the metal at its upset ends.

The defect above noted has been overcome by my present invention, whichconsists, briefly stated, in elevating the middle bar of the buckle asmuch as possible with safety by upsetting its ends and in supplementingthe elevation so obtained, to increase the effective height of the bar,

by pressing up in the material of the bar a hollow longitudinal rib orhump.

In the accompanying drawing Fig. 1 is a plan View of my improved buckle;Fig. 2 is a sectional View thereof on the line 2-2 of Fig. 1; and Fig. 3is a sectional View, similar to Fig. 2, of a slightly modified form ofthe buckle with a strap attached to its rear bar and another strapthreaded through its slots and over the middle bar.

As therein shown, the one-piece buckle, which is stamped from a plate ofsheet metal, consists of front and rear transverse bars a and b and amiddle or intermediate transverse bar c, which as usual are connected attheir ends by side pieces and provide two intermediate slots d and e.The middle bar' is pressed up into a plane slightly elevated above theplane of the main body portion of the buckle, which is substantiallyflat, with the formation of bends f, f in and a consequent stretching ofthe metal at its ends. where they join the two side pieces, and a hollowlongitudinal rib or hump g is pressed up in the bar, thereby giving itadditional eifective height.

In the modification illustrated in Fig. 3 the innei1 end of the frontbar a is provided with an integral downturned lip, or teeth h; and thereis here shown a strap i which is attached to the rear bar b and a secondstrap j which is threaded through the slots and over the middle bar.

What I claim as new, and desire to secure by Letters Patent, is-

1. An integral slide buckle which is stamped from a plate of sheet metaland has three transverse bars and two transverse slots, the middle barthereof being upset at its ends into a plane above that of the otherparts of the buckle and further effectively elevated thereabove by anupwardly projecting longitudinal rib upset therein and the slot betweenthe middle and the front end bar being of a width not substantiallygreater than the total elevation of said middle bar.

2. An integral slide buckle which is stamped from a plate of sheet metaland has three transverse bars and two transverse slots, the middle barbeing upset at its ends into a plane above that of the other parts ofthe buckle and further elevated thereabove by a longitudinal rib upsettherein and so confined as to leave flat marginal portions on both sidesof said bar and the front end bar having a downturned element at itsinner edge and forming with the middle bar. a slot of a width notsubstantially greater than the total elevation of said middle bar.
